[Radiograms of the paranasal sinuses as a principle of identifying catastrophe victims and unknown skeletons]

The paper is devoted to the identification on the base of X-ray of frontal sinuses. These sinuses, developed in puberty doesn't change its shape during aging. Differentiation of the size and shape of sinuses is remarkable and probably is one of the individual features of the man. The system of classification of sinuses is proposed, basing on the area size, shape and symmetry. In the current everyday practice all X-ray radiograms are destroyed after five years of storage in Poland. For identification purpose all radiograms of sinuses and A-P punctures of skull should be stored in radiology departments, and arranged according to proposed classification system. The case is presented, in which the pictures of skull were the base of successful identification of skeleton.
